IB Chemistry SL 2013-2015 Taewoong Moon Oxidation- Reduction Reactions- Design Lab Experiment Question: In oxidation-reduction reactions‚ or redox reactions‚ are strengths of reducing and oxidizing agents different from each reaction? Theory of an experiment: 1. Determine the relative strengths of oxidizing agents and reducing agents. 2. Study some simple oxidation-reduction reactions Hypothesis: Relative strengths of reducing and oxidizing agents differ from each reaction. Background Information:
Free Oxidizing agent
Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

study of the interchange of chemical and electrical energy OIL RIG – oxidation is loss‚ reduction is gain (of electrons) Oxidation – the loss of electrons‚ increase in charge Reduction – the gain of electrons‚ reduction of charge Oxidation number – the assigned charge on an atom Oxidizing agent (OA) – the species that is reduced and thus causes oxidation Reducing agent (RA) – the species that is oxidized and thus causes reduction ELECTROCHEMISTRY INVOLVES TWO MAIN TYPES OF PROCESSES: A. Galvanic (voltaic)

Abstract Chemical reactions can be used to produce electricity and electricity can be used to cause chemical reactions through oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the

Chemistry assignment Introduction: Throughout modern day society metals are constantly used‚ in fact mankind has been heavily dependent on metals for the last several hundred years. But the science behind metals has only been discovered in recent years and has now become known to people that we simply could not live without them. Metals make up around 80% of the elements (currently discovered). They are used in everyday items that society depends on‚ such as: cars‚ re-bars for building‚ window

classify chemical reactions in various ways. Often a major classification is based on whether or not the reaction involves oxidation-reduction. A reaction may be classified asredox in which oxidation and reduction occur or nonredox in which there is no oxidation and reduction occurring. Redox Reactions A redox reaction can be recognized by observing whether or not the oxidation numbers of any of the elements change during the
Premium Chemical reaction
Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical
